I 0 aZZ whom it may concern:

' Be it known thatI, HARRY'V. BROWN, a citizen of thc'United States, anda resldent of Oklahoma city, in the county of Oklahoma and State ofOklahoma, have invented certain Improvements in Machines for MakingBrick, of which the following is a specification, reference being hadtothe accompanying drawings.

The invention pertains to machines for making concrete brick and blocks.

Machines of this class commonly include i a mold supported in positionto have the concrete delivered "into it manually or by a feedingmachine.

After the concrete has been placed in the mold, it IS necessary to tampor firmly pack itin order thatit be removed as a 1 finishedbrick andplaced for drying; and

when brick with a special finish face is to be made it is necessary tofirst place in the mold a quality oi? concrete especially pre pared andmixed for said finish.

' i-tl'terthe mold is completely filled and tanipcd, the surplusconcrete'is stroked off with a straight-edge and the finished brick isremoved. I 1

in machines of this class heretofore used, one person is employed toattend to the filling of the mold; another to stroke offj the surplusconcrete; and another to remove the j finished brick; with the resultthat While the finished brick maybe produced. a little quicker by thecombined efforts of the several persons than by one alone they areWaiting on each othera greater portion of their individual time brickproduced is not. in proper proportion to the number of personsenuployed.

7 An object, therefore, of the invention is to provide a machine Whoseoutput of brick will be greater in proportion to the numberof'personsemployed in its operation.

Other objects and advantages of the invention will be set forth in theensuing description.

Figure l of the drawings is a planvieW of the improved machine.

Figure 2 is a similar view, but With certain molds and their supportingbrackets swung to different positions.

and the number of Figure 3 is an elevationview of'the -machine, with theparts in-the position shown in Figure 2- I i r Figure 4 is areproduction of a Figure 3 on largerscale.

Figure 5 scale as Figure 4 of Figure 2. r y

In carrying out the objects stated, the inventor providesas many moldsas there are operations to be carried out in properly filling a'mold andremoving the finished brick, and arranges said molds so that they may becirculated along fa predetermined path of movement.

iS'a sectional View on'thesameand-taken on the line 5-5 With the machinearranged' in -this Way,

one person may attend tosthe filling of the" mold; another to thestroking of the mold,

and another to removingthe brick.

In arranging the several'molds to' 'circulate, a vertical center-post10'is provided and set firmly ample in a cast-ironfoot -plate" onconcrete 12 inthe ground.

in a" suitable footing, for eX-' igresting This center-postldis"arranged asa vertica-l' spindle and has a number of'supportingbrackets pivotally' embracing it ash n I Each ott'he'brackets isofzwhich that are three-inthisinstance, is formed into a I fmold 14 at aconvenient radial distance from i the center-post 10, and While saidbrackets and molds cannot pass each other in their movements around thecenter-post their a movements are otherwise wholly independent of eachother and.

mold can pass over it. v

In this instance this support includes an arcuate ra1l 1 5 wh ch 18concentrlc to the center-post 10 and supported at its end by posts 16and 17 set in the concrete 12.

These posts 16-and 17 are connected to the foot-plate =11 bv radialbraces 18 and 19, re-' spectively.

are produced manually and at the convenience of the persons filled, a.sup- I At the end of the rail on which a mold 14: approaches it, aleaf-spring finger is bolted to its supportingpost 16, the upper or freeend of this finger extending up along the outer face of the rail andabove said rail in position to engage a notch 21 in a looking bearing 22on the outer end of each mold.

When a mold 14 is swung onto the rail 15, the sloping surface 23 of thebearing 22 swings the finger 2O outward to where it will fall into thenotch 21 by its own elasticity, and the mold is thus releasably lockedin position to be filled.

During the fillinglof the mold 14 and the tamp-ing or its contents, therail 15 bears the strain that would otherwise be brought onto itssupporting bracket 13 and onto the center-post 10. 7

By manually releasing the locking engagement ofthe'finger 20, the filledmold 14- may be advanced in the direction of the arrows 24;; Y v

To stroke the surplus concrete 25 from the filled mold 14, astroking-bar 26 is supported in position to have the mold pass under itimmediately upon leaving filling position; and in this instance saidstroking-bar is adjustably bolted toan arm'27 which radiates from thecenter-post 10.

The arm 27 adjustably embraces the center-post 10, and is provided'witha set-screw 28 to clamp inplace thereon.

By drawing. the filled mold 14- under the stroking-bar 26 the surpluscontents 25 is scraped off and falls to the ground.

After passing under the stroking-bar 26, each mold 14; is moved along tothe advance end of the rail 15 where thenotch 21 in its locking bearing22 is engaged by a second leaf-spring finger 29 bolted to the post 17.

The bottom 30 and advancing sidewall 31 of each mold 14 are connectedtogether integra-lly or in some other rigid manner as best shown inFigure 5, and at their angle they are hinged to the remaining portion ofthe mold by pins 32 -which pass pivotally through 33. V v i I Thisarrangement allows the bottom 30 to be swung upward and the wall 31outward,

and thereby facilitates the removal of the finished brick.

The swinging movement of the bottom 30 to unloading position is limitedat the proper time by an arm 34 which is cast on its lower face andabuts the lower edge of the side wall 35 of the mold 14'. v v

The wall 31 is provided with a handle 36 for swinging it and the bottom30.

To aid in swinging the bottom 30'upward, a verticallymovable plunger 37is provided, the upper end of this plunger fitting slid.-

ably through a bearing 38 bolted. to the in-' side of the rail 15 andthe lower end pivoted toa toot lever 39 which is fulcrumed to a bearing40 on the radial brace 19.

During the time the molds llare being swung from unloading positionaround to 1. In a machine for making brick, a pivot centre, moldsupports pivoted to and radiating therefrom, molds on the free ends ofsaid supports, a fixed stroking bar in the path of the molds and beneathwhich they pass, a locking bearing on each mold, and means automaticallyengaging thesameafter the;

mold passes the stroking bar.

2. In a brick making machine, a rotary mold, a locking bearing on theend thereof and having a notch, a spring finger for engagement with saidnotch,- a second spring finger for engagement with said: notoh,fand' astroking bar disposed betweensaid fingers.
